DESCRIPTION

The core of the PMA 45K1 is the patented magneto dynamic oxygen measuring cell. The measuring
principle is one of the most precise methods for the volumetric determination of the oxygen content in
the measuring range of 0-100 vol% O .

The oxygen analyzer PMA 45K1 is designed for the stationary use and can also be applied in nuclear
installations. The characteristics of this analyzer are overpressure security up to 16 bar as well as a
guaranteed leak tightness with a leak rate of less than 10 -6 mbar l/s.

The transmitter is set to a temperature of +55 °C. The temperature regulator is constructed such as
the low voltage device and the 115/230 V power part are separated via an opto-isolator with no volt-
age switch.
A non-reversible overpressure fuse avoids that the transmitter is overheated above 72 °C.
The great surface heating elements mounted on the transmitter surface guarantee a quick and con-
stant temperature circulation.
In order to ameliorate the heat storage and isolation, the transmitter is equipped with an insulation
cover.
